Road building is only available for Mancer Pioneers. Mancer is the race of the Capitar faction.

Not exactly. There are two possible ways of getting the Road building ability. A rare Path of the Governor trait and the Pioneers of the Mancer race. The OP asked specifically about the ability for Pioneers.

That is exactly what I said Gaunathor, so why are you saying not exactly>>

This is what I said:

"Road building is also available to path of the governor heroes who get the ability."

Where I say "Also available" That means that this is the second way, the mancer pioneers being the first way.

I then said "path of the governor heroes who get the ability" This means that heroes who take the path of the governor path can get the ability to build roads if they choose it. So where was I wrong>

My apologies. I read "only" instead of "also".

I just got the Roads trait in a Governor heroe, for testing purpose. It is so cool to have now the skill of making my wished roads...

but why only a Hero, governor, and with the road trait? Isn't it weird? I'm having a hero just for building roads...Roads should be considered for all pioners, and not only for mancers...

About that, they should build the outpost (1-3 turns) instead of consuming in the process... so many pioneers are needed...

By the way, now that seems that roads are going to be introduced, think in taking more time depending on terrain...my horsed hero made 4 roads per turn...so I will make a highway to connect the map from one side to the other in little time
